Influence of individual values on attitudes toward corruption: What undermine formal anticorruption effectiveness

The causes of corruption are often researched by scholars from the macroscopic perspectives of institutional and cultural factors. Neglected is scholarship on the relationship between individual values and corruption. People’s definitions and attitudes toward corruption are largely determined by personal values. However, scarce scholarly attention has been paid to what and how value factors exert influence on people’s attitudes toward corruption and how values moderate the relationship between the effectiveness of formal institutions against corruption and people’s anticorruption willingness. Drawing on the first‐hand survey data collected among Chinese civil servants, this research explores the impact of civil servants’ values on their tolerance towards corruption and willingness to engage in anticorruption. Adopting Hofstede’s (1984) four values model (power distance, collectivism, uncertainty avoidance, and masculinity), this study reveals that respondents high on collectivism or masculinity hold higher corruption tolerance and lower willingness to participate in actions against corruption whereas uncertainty avoidance is negatively related to corruption tolerance and positively associated with the respondents’ willingness to engage in anticorruption. Furthermore, the values serve as moderating roles in the relationship between formal anticorruption effectiveness and civil servants’ willingness to engage in combating corruption. Specifically, both collectivism and masculinity dilute the positive impact of the government’s anticorruption effectiveness on anticorruption willingness.

Perception of warble song in budgerigars (Melopsittacus undulatus): evidence for special processing

The long, rambling warble song of male budgerigars is composed of a large number of acoustically complex elements uttered in streams lasting minutes a time and accompanied by various courtship behaviors. Warble song has no obvious sequential structure or patterned repetition of elements, raising questions as to which aspects of it are perceptually salient, whether budgerigars can detect changes in natural warble streams, and to what extent these capabilities are species-specific. Using operant conditioning and a psychophysical paradigm, we examined the sensitivity of budgerigars, canaries, and zebra finches to changes in long (>6?min) natural warble sequences of a male budgerigar. All three species could detect a single insertion of pure tones, zebra finch song syllables, budgerigar contact calls, or warble elements from another budgerigar’s warble. In each case, budgerigars were more sensitive to these changes than were canaries or finches. When warble elements from the ongoing warble stream were used as targets and inserted, out of order, into the natural warble stream so that the only cue available was the violation of the natural ordering of warble elements, only budgerigars performed above chance. When the experiment was repeated with all the ongoing warble stream elements presented in random order, the performance of budgerigars fell to chance. These results show species-specific advantages in budgerigars for detecting acoustic changes in natural warble sequences and indicate at least a limited sensitivity to sequential rules governing the structure of their species-specific warble songs.     

Analyzing Youth’s Activity Patterns in Campus Open Spaces Depending on Their Personal and Social Needs

Campus open spaces play an important role in meeting socialization and personal development needs of youth. Various studies have shown that space use of youth is different from that of general society: particularly their psychosocial nature and the activities they carry out toward this nature differ from those of the children and adults. However, only a limited number of studies have produced findings on the needs of youth toward obtaining gains related to development of psychosocial nature required to carry out the activities aimed at meeting such needs. This study analyzed the use of campus open spaces by youth. The most preferred 3 places in study area have been chosen, and with behavioral observation, the activity types occurred in these places were identified. Which of these activities are for personal development and which of them are for social development were determined.     

Category-selective attention modulates unconscious processes in the middle occipital gyrus

Many studies have revealed the top-down modulation (spatial attention, attentional load, etc.) on unconscious processing. However, there is little research about how category-selective attention could modulate the unconscious processing. In the present study, using functional magnetic resonance imaging (fMRI), the results showed that category-selective attention modulated unconscious face/tool processing in the middle occipital gyrus (MOG). Interestingly, MOG effects were of opposed direction for face and tool processes. During unconscious face processing, activation in MOG decreased under the face-selective attention compared with tool-selective attention. This result was in line with the predictive coding theory. During unconscious tool processing, however, activation in MOG increased under the tool-selective attention compared with face-selective attention. The different effects might be ascribed to an interaction between top-down category-selective processes and bottom-up processes in the partial awareness level as proposed by Kouider, De Gardelle, Sackur, and Dupoux (2010). Specifically, we suppose an “excessive activation” hypothesis.     

Knowledge-How and Performance Success

Anti-intellectualists claim that knowledge-how requires at least a corresponding ability or performance success that includes non-intellectual components. They argue that an insistence on the close relationship between knowledge-how and performance success is needed to account for our intuitions on the practical aspects of knowledge-how. In this paper, we examine three main anti-intellectualist proposals for what constitutes performance success, those of Hawley (2003), Noë (2005), and Kumar (2011), and argue that all of them are non-informative in a practical manner. We further point out that the problem of non-informativeness is dominant in anti-intellectualism.

教师和家长关于儿童入学准备观念的调查研究

本研究对218名家长和370名教师进行了问卷调查。从身体和运动发展、情绪和社会性发展、学习方式、言语发展、认知发展和一般知识基础、家庭6个维度,考察了家长和教师对儿童入学准备的看法,并比较了家长、幼儿教师和小学教师对儿童入学准备观念的差异。结果发现:(1)整体上看,家长、幼儿教师和小学教师最重视身体健康、注意力、教养方式、自信心、学习兴趣、会听课等方面的问题;(2)幼儿教师和小学教师有关儿童入学准备的观念比较接近,而小学教师相对重视服从权威、父母教育程度、文明礼貌、自我中心和表达能力等方面的问题;幼儿教师相对重视抗挫折能力、亲子关系、学习态度、自我控制、身体健康等方面的问题;(3)家长与教师的观念在整体上存在显著差异。
